摘　　要：试验研究了EPS粉煤灰砂浆的耐久性能,主要包括耐水、干缩和抗腐蚀性能。结果表明:随着EPS掺量的增加,EPS粉煤灰砂浆的吸水率减小,软化系数增加;干燥收缩值明显降低;抗化学腐蚀性能提高,试样表面粉化程度减弱。Experimental study was performed on the durability properties of EPS fly ash mortar such as water-resistance,drying shrinkage and corrosion resistance properties.The results showed that with the increase of the ratio of polymer,the water absorption of EPS ash fly mortar reduced,soften coefficient increased,drying shrinkage decreased significantly,corrosion resistance increased,atomize of sample surface weakened.
